The purpose of the study was to compare measures of isometric static muscle strength obtained with three commonly used sets of instructions. Maximum voluntary hand-grip strength and time to reach maximum strength were measured on 34 Army personnel. All three instruction conditions yielded reliable measures of strength and time-to-maximum output. The variability of the data, however, differed appreciably among the instruction conditions. The results emphasize the necessity for explicit instructions to the subjects in strength assessment studies, and the importance of reporting in detail all factors which might influence the measure obtained.
